I have an authentic baseball-sleeve style tshirt from the closing of Winterland (New Year's Eve 1978) - Grateful Dead, Blues Brothers & NRPS. I purchased this at the concert myself. It is well worn and thin, but has no holes or tears. This is not the replica that shipped with the DVD in 2003, but the real concert T! I can't find one anywhere, so it's obviously pretty rare. BTW, photos are a bit dark - sleeves are blue, not black. Any guidance on pricing would be greatly appreciated.
